Field Detail

path2

protected Path path2

Line of Contact is drawn with two paths. The super class manages the first path; this is the second.

Constructor Detail

LineOfContact

public LineOfContact(String sidc)

Create a new graphic.

Parameters:

sidc - MIL-STD-2525C identifier code.

Method Detail

doRenderGraphic

protected void doRenderGraphic(DrawContext dc)

Description copied from class: PhaseLine

Render this graphic, without modifiers.

Overrides:

doRenderGraphic in class PhaseLine

Parameters:

dc - Current draw context.

See Also:

AbstractTacticalGraphic.doRenderTextModifiers(gov.nasa.worldwind.render.DrawContext), AbstractTacticalGraphic.doRenderGraphicModifiers(gov.nasa.worldwind.render.DrawContext)

generateIntermediatePositions

protected void generateIntermediatePositions(DrawContext dc,
                                             Iterable<? extends Position> positions)

Generate the positions required to draw the line.

Overrides:

generateIntermediatePositions in class ForwardLineOfOwnTroops

Parameters:

dc - Current draw context.

positions - Positions that define the polygon boundary.

generateParallelLines

public void generateParallelLines(Iterator<? extends Position> iterator,
                                  List<Position> leftPositions,
                                  List<Position> rightPositions,
                                  double halfWidth,
                                  Globe globe)

Create positions that describe lines parallel to a control line.

Parameters:

iterator - Iterator of control line positions.

leftPositions - List to collect positions on the left line.

rightPositions - List to collect positions on the right line.

halfWidth - Distance from the center line to the left or right lines.

globe - Current globe.

generateParallelPoints

protected void generateParallelPoints(Vec4 point,
                                      Vec4 prev,
                                      Vec4 next,
                                      List<Position> leftPositions,

                                      Globe globe)

Compute points on either side of a line segment. This method requires a point on the line, and either a next point, previous point, or both.

Parameters:

point - Center point about which to compute side points.

prev - Previous point on the line. May be null if next is non-null.

next - Next point on the line. May be null if prev is non-null.

moveTo

public void moveTo(Position position)

Move the shape over the globe's surface while maintaining its original azimuth, its orientation relative to North.

Specified by:

moveTo in interface Movable

Overrides:

moveTo in class ForwardLineOfOwnTroops

Parameters:

position - the new position of the shape's reference position.
